Follow-up: the teacher is that it usually walks.
Answer: the kitten walks without sound.
That's because the inner cat's paws have a very soft meat pad. This layer of meat pad can not only cushion the cat from jumping from a height, but also make it walk quietly, so as to get closer to the prey without being noticed. Therefore, the cat walks silently because its paws have unique meat pads at work, and the cat's tail also has strong balance ability, which also plays a certain role in its silent walking.
Follow-up: Then he is asleep!
Answer: If you pay attention to sleeping cats, you will find that when they sleep, the slightest sound will wake them up. This is because cats sleep in shallow sleep and deep sleep. Many times, cats seem to be asleep, but they still maintain a high degree of vigilance. Cats don't get enough rest during light sleep, which is equivalent to a nap. Cats are in a deep sleep only when they are really relaxed. Cats who sleep deeply generally adopt very comfortable postures, such as twisted supine, while cats tend to lie prone when they sleep lightly. Cats sleep from shallow sleep to deep sleep and then to shallow sleep in turn. The shallow sleep takes a long time, so there is not much time to really rest and relax. Pet cats really sleep and rest for only 5 or 6 hours every day.
